Abstract
Aim: In case of liquidation of residual pollution which can not be removed by mechanical and physical methods, comfortable in the use can be decontaminating foams. In contrast to the solutions of disinfecting, foams may remain long on surfaces: vertical, inclined and ceilings. Important practical advantage of the use of foams is their visibility, which is especially important when operations are performing on large surfaces and spatial constructions. Decontaminating foams can be prepared by using commercially available equipment and special preparations. Generally active chemical agents are added to the solution of special foam concentrates. Especially noteworthy are concentrates based on cationic surfactants with good biocidal properties, even without the special additives. These foams could be useful for example during operations decommissioning outbreaks of avian influenza in 2007, when a large volume chicken coops were disinfected. Necessity of carrying out the decontamination operations on a large scale occurs fortunately rarely thus maintaining the special equipment and preparations for the production of active foam is usually not appropriate. You can, however, produce relatively stable decontaminating foams, using standard S-foaming agents, and easily available substances as acids, bases and oxidizing agents, using foam equipment used in fire-fighting operations. The research confirmed the effectiveness of such foams in removing chemical and biological pollution.
